This series IC is a PWM type DC/DC converter for AC/DC which provides an optimum system for various electrical product. It supports both isolated and nonisolated devices, enabling simpler design of various types of low power consumption electrical converters. This series also has a built-in starter circuit that can withstand up to 730 V, which contributes to low power consumption. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. Switching frequency is fixed at 100 kHz. At light load, the switching frequency is reduced and high efficiency is achieved. A frequency hopping function is also built-in, which contributes to low EMI. In addition, this product has a built-in super junction MOSFET which has a withstand voltage of 730 V.
You can choose from a variety of power and topology evaluation boards.
